I don't think it really makes it stronger, it stiffens the blade while lightening it a small amount. By adding ridges it will take more force to get it to bend, but I don't think it will increase the amount of force needed to make it take a set or break it. Theoretically it reduces the amount of surface an object touches when the knife passes through it, reducing drag. ymmv.

So, any physics professors in the group? Cause I had always thought this was true.
